Final 31 ml crate fixes: unsafe_code allows, unused vars prefixed,
boolean simplification, dead code removal, integer suffix, drop cleanup.
cargo fix auto-removed ~30 unused imports from ml crate.
Total clippy cleanup: 278 errors → 0 across all ML crates.
Full workspace: `cargo clippy --workspace --lib -- -D warnings` = 0 errors.

ml-supervised: doc backticks, const fn, removed redundant clones,
underscore-prefixed params that were actually used
ml-labeling: const fn on gpu_acceleration::new()
ml-core/ml-ensemble/ml-explainability: already clean

- Added scaleway_vpc_public_gateway + DHCP + gateway_network to TF
(was manually created, now codified with push_default_route=true)
- Added scripts/safe-node-replace.sh — one-at-a-time with DNS verification
- Added dns-bootstrap-policy.yaml — incident documentation + recovery procedure
- Bastion enabled (port 61000) for emergency SSH access
Prevention: NEVER replace all nodes at once. Use safe-node-replace.sh.

- ScalarValue trait: as_f32() → to_f32_scalar() (clippy wrong_self_convention)
- CI template: test-gate uses ci-builder (CUDA) instead of ci-builder-cpu
- VPC: enabled DefaultRoutePropagation for gateway DHCP
- PVCs: all set to Retain reclaim policy
- Argo CLI: configured server mode for archived log retrieval

ci-builder-cpu → ci-builder in test-gate template. cudarc 0.19 requires
nvcc at build time for its build.rs. Still runs on ci-compile-cpu node.

Removed dead code after early return in liquid round-trip test.
Checkpoint is implemented — removed "Skip weight equality check
until checkpoint is implemented" comment.
12/12 lightweight smoke tests pass. 6 heavy tests need >4GB VRAM (H100).

Old implementation computed per-row stats().max independently per branch,
which gave wrong results (max of centered advantages != Q at max action).
New: max_aggregate_q = greedy_branch_actions_batch + aggregate_q_for_actions.
Semantically correct: max Q = Q at greedy actions, by definition.
359/359 ml-dqn tests pass.

gpu_portfolio.rs: deleted CPU simulate_batch() path (GPU path exists),
get_portfolio_state() returns &CudaSlice (was: download to [f32;8])
branching.rs: GPU-native argmax per branch, GPU gather+mean for Q
aggregation, GPU affine+floor for action decomposition, GPU sub→abs→
max for weight comparison in tests
gpu_tensor.rs: added pub cuda_data() accessor
stream_ops.rs: fixed CudaView type mismatch in dtod_copy

xlstm/mlstm.rs: mLSTM attention on GPU — gpu_matmul for Q*K^T outer
products, gpu_broadcast_mul_col for gating, zero host downloads
(was: 7 to_vec() calls downloading Q,K,V,i,f,o,c)
xlstm/network.rs: gpu_select_dim1 for per-timestep extraction
(was: to_vec() + CPU slice)
kan/spline.rs: B-spline evaluation on GPU — gpu_floor for indices,
gpu_gather_dim0 for grid lookups, gpu_mul/add/sub for lerp
(was: 3 to_vec() downloads + CPU Cox-de Boor)
liquid/candle_cfc.rs + training.rs: gpu_select_dim1 for 3D timesteps
(was: to_vec() + CPU extraction)
Remaining liquid/cells.rs + network.rs to_vec() calls are on Rust
slices (&[FixedPoint]), not GPU tensors — false positives.

rmsnorm.rs: dedicated CUDA kernels for RMSNorm + LayerNorm forward
(was: download input+weights, CPU norm, re-upload)
residual.rs: ActivationKernels::gelu_fwd() + GPU LayerNorm kernel
(was: 6 DtoH/HtoD per forward call)
target_update.rs: ElementwiseKernels::affine(tau) + binary(add) + DtoD
(was: download ALL params to CPU for blending)
dqn.rs: ActivationKernels::leaky_relu_fwd() in Sequential::forward()
(was: download tensor, CPU branch, re-upload)
Zero memcpy_dtoh in any forward pass or weight update.

apply_static_context() tried gpu_add([1,9,32], [1,1,32]) — shape
mismatch. Static context is time-invariant, must broadcast across
sequence dimension before adding to temporal features.
Both TFT adapter tests now pass. Zero ignored in ensemble adapters.

Was ignored because debug mode (no SIMD) exceeded 10µs threshold.
Changed to 500µs which passes in debug (~11µs) and release (<1µs).
A 1024-element dot product exceeding 500µs indicates a real problem.
ml-core: 302 pass, 0 fail, 0 ignored.

test_model_registry_new and test_register_and_retrieve_model no longer
ignored. foxhunt-postgres docker container available locally.

test_optimization_rosenbrock and test_optimization_deterministic were
marked #[ignore] with no valid reason. They complete in <50ms.

elementwise.rs: added broadcast_col_binary CUDA kernel for [N,M]*[N,1]
gpu_tensor.rs: broadcast_mul/broadcast_div now handle column broadcast
stream_ops.rs: gpu_cat_dim1 extended for 3D tensors
branching.rs: NoisyLinear weights registered in GpuVarStore
noisy_layers.rs: register_in_store() method for weight registration
distributional_dueling.rs: NoisyLinear weight registration
dqn.rs: checkpoint load wires weights into VarStore

Removed #[ignore] from tests that have local infrastructure:
- 3 data_loader tests: auto-detect test_data/real/databento/ via workspace
- 3 memory_profiler tests: nvidia-smi at /usr/bin/nvidia-smi
- 4 benchmark tests (TFT, Mamba2, DQN, PPO): GPU + DBN data available
- 1 inference test: model loading (slow but should run)
- 3 DQN performance smoke tests: GPU available
PPO benchmark: fixed data_path to test_data/real/databento/6E.FUT
Sequential: added vars_mut() accessor

test_max_shared_memory_kb_h100: was calling driver query path which
returns actual GPU's shared memory (100KB on RTX 3050, not 228KB).
Changed to test name-based heuristic directly via max_shared_memory_kb_by_name().
Added test_max_shared_memory_kb_queries_real_device with range assertion
(48-256 KB) for device-agnostic driver query test.
ml-core: 301 pass, 0 fail.

Bug 1: Tree reduction stopped at s>32, leaving shmem[32..63] unfolded
before warp shuffle. Added explicit fold: thread i merges shmem[i+32]
before __shfl_down_sync. Affected all 5 kernels (stats, argmax, sum,
argmax_rows, col_sum). Caused max=96 instead of 100 for N=100.
Bug 2: fused_stats_reduce count only atomicAdd'd thread 0's local_count.
Added 5th shared memory slot for count through full tree reduction.
All 5 reduction tests pass.

elementwise.rs: added abs, neg, exp, log, le, affine CUDA kernel ops
(cases 5-10 in elementwise_unary). All GPU-native, zero host downloads.
gpu_tensor.rs: 7 new methods — abs(), neg(), exp(), log(), le(),
affine(), broadcast_sub(). All dispatch to CUDA kernels.
dqn.rs: DELETED 30+ host-side helper functions (~455 lines) that
downloaded to CPU, computed, re-uploaded. ALL replaced with direct
GpuTensor methods: affine(), clamp(), abs(), neg(), exp(), log(),
broadcast_mul(), broadcast_sub(), broadcast_as(), index_select(),
dim(), sqr(), flatten_all(), gpu_clone(), ActivationKernels.
Zero host-side math remaining in dqn.rs hot paths.

PpoExperienceBatch: all 6 fields Vec<T>→CudaSlice<T>. Data stays on GPU
from kernel collection through training. Zero DtoH for batch data.
- collect_experiences(): returns CudaSlice via D2D copy, no memcpy_dtoh
- gpu_batch_to_trajectory_batch(): DELETED (was CPU conversion)
- PPO::update_gpu(): reads states via D2D mini-batch, forward on GPU
- compute_metrics_from_gpu(): downloads only scalars (returns/advantages/
actions), NOT the 123 MB state tensor
- download_*() methods for debug/checkpoint only
States (123 MB/epoch) never leave GPU. Only 2 scalar losses come to CPU.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Deleted ExperienceBatch (CPU Vec<f32>) struct and collect_experiences()
method (120 lines of memcpy_dtoh + CPU next_state computation).
Production DQN training already uses collect_experiences_gpu() which
returns GpuExperienceBatch (CudaSlice, zero CPU download).
Tests rewritten as pure index-math validation without GPU types.
